给水管网GIS和水力模型无缝连接的方法研究

在如何利用给水管网信息管理系统(GIS)中的信息建立水力模型的研究中,传统方法容易导致水力模型继承GIS中的数据缺陷和错误,也不能保持模型和GIS系统的同步更新。文章提出建立共享数据库的方法,解决了此类问题,实现了给水管网GIS和水力模型之间的无缝连接。同传统方法相比,建模结果更准确,而且减少了重复开发、节约了项目投资。

Research on seamless integration of GIS of water supply network and hydraulic model

In the research on the construction of hydraulic model with the database of the GIS of water supply network,the disadvantages of the traditional method,such as: easy to cause defects and mistakes when hydraulic model inherit data from the GIS,can't realize data synchronization over the model and the GIS were disclosed.Constructing a sharing database can be a useful method to solve the above problems,and then,realize the seamless integration of GIS of water supply network and hydraulic model.Compared to the traditional method,this method not only has advantage in more accurate model result,but also reduces the repeat exploitation,save the investment cost of the project.
